LAMP-BURNER.

To all whom it may concern:

Be it known that I, ARTHUR H. CooMs, a citizen of the United States, andresident of St. Louis, Missouri, have invented certain new and usefulImprovements inf Lamp- Burners, of which the following isa specicationcontaining a full, clear, and exact description, reference being had tothe accompanying drawings, forming a part hereof.

My invention relates generally to lamp burners, and more particularly tomeans attached to a lamp burner for regulating and adjusting the flamefrom the lamp wick, the object` of my inventionbeing to equip anordinary form of lamp burner with simple, inexpensive means whereby theflame'from the lamp wick can be accurately adjusted and regulatedregardless of the condition of that portion of the wick which projectsabove the wick tube.

It very frequently happens that in trimming a lamp wick one corner isleft slightly and when the wick is lighted an uneven liame is theresult, and it is the purpose of my invention to equip the wick tubewith independently operating members which can be raised and lowered soas to cut off and regulate the llame from the wick.

To the above purposes, my invention consists in certain novel featuresof construction and arrangement of parts which will be hereinafter morefully set forth, pointed out in the claims, and illustrated in theaccompanying drawings, in which:

Figure l is an elevation of a portion of a lamp and burner, and with theburner cap shown in vertical section; Fig. 2 is a hori- Zontal sectiontaken on the line 2-2 of Fig. l; Fig. 3 is a section taken on the line 33 of Fig. 2; and Fig. 4 is a vertical section similar to Fig. 3, andshowing a modified form of the burner. K

Referring by numerals to the accompanying drawings: l designates thebowl or body of the lamp, 2 the body of the burner, 3 the perforatedplate which supports the lamp chimney at, and through the center ofwhich plate passes the wick tube 5.

6 designates the ordinary burner cap, which is hinged to one side of theplate 3, and in the top of which cap is formed the tnansverselyVdisposed flame opening 7. Thel Haine regulating members 8 are formed ofSpecification of Letters Patent. Application mea February 19, 1909.serial No.

plates of thin sheet metal, which are bent into such shape as to fitsnugly against the wick tube 5 above the plate 3, the inner ends ofsaidl plates meeting at the center of the wick tube, and formed integralwith and projecting outwardly from the outer ends of these members arepins 9. 'The members S are free to slide vertically and independentlyupon the wick tube 5.

The means employed for operating the llame regulating members comprisesa pair of independently operating rods or levers l0, which occupypositions beneath the plate 3, and each rod being bent laterally, asdesignated by ll, and said laterally bent portion being journaled on theplate 3 immediately in front of the corresponding side of the wick tube,and formed in this laterally bent portion 11 lis a loop 12, whichextends upward and rearward, which receives the corresponding one of thepins or lugs 9. Thus when the outer ends of the members 10 are engagedand raised or lowered, the laterally bent portions 11 are rocked intheir bearings on the plate 3, and the loops l2 are correspondinglyraised and lowered, thus imparting a corresponding movement to themembers 8.

In case the lamp wick has been trimmed so as to leave one side thereofhigher than the other, trimming flame on the corresponding side of theburner, the corresponding member 8 is slightly elevated by actuating thecorresponding rod or member 10, and as said member 8 is ele vated thecorresponding portion of the projecting wick is partially covered, thuscutting down the flame on this side of the wick. The members 8 operateindependently, and therefore the flame can be very accurately regulated.

In Fig. 4 I have shown a burner as provided with a pair of the caps 6,and where such construction is used the flame is comparatively strongerthan where a single cap is used, and is not easily affected by suddendrafts of air passing through the burner or into the chimney.

A lamp burner of my improved construction is simple and inexpensive, iseasily manipulated, and provides means whereby the fiame from the lampwick may be accurately regulated. When the wick is turned low so thatthere is but a small flame issuing thereas shown in Fig. l, which unevenresults in an extended pointl of from, the ame can be cut off and thelamp put out by operating the rods 10 so as to simultaneously elevatethe members 8, and

V and the wick tube thereof, of a pair of independently operating flameregulating members arranged for vertical movement on the upper end ofthe wick tube, and means whereby said members are actuated.

3. A device of the class described, comprising a burner, a wick tubetherein, a pair of independently operating members operating on theupper portion of the wick tube, and which members together inclose thewick tube, a pin carried by each member on the edge thereof, and aslotted lever for operating each member, in the slots of which said pinsare located.

4. A deviceof the class described, comprising a burner, a wick tubetherein, a pail' of independently vertically operating members operatingon the upper portion of the wick tube, a pin carried by each member onthe edge thereof, and a slotted lever for operating each member, in theslots of which said pins are located.

n testimony whereof, I have signed my name to this specification, inpresence of two subscribing witnesses.
